数感是新课程标准提出的十大核心概念之一,是小学生数学核心素养的一个重要方面。但是当前教学中,很多教师并没有意识到培养数感的重要性,忽略了数感的培养。同时,数感又是不具体的虚化的概念,因此对教师来说,如何培养学生的数感是个亟待解决的问题。本文笔者从数感的定义出发,结合中低年级数学的内容,提出几点关于小学生数感培养的策略。
Number sense is one of the top ten core concepts proposed by the new curriculum standard, which is an important aspect of pupils’ core literacy. However, in the current teaching, many teachers do not realize the importance of cultivating sense of number, ignoring the sense of number of training. At the same time, the sense of number is not specific concept of virtualization, so for teachers, how to develop a sense of the number of students is a problem to be solved. In this paper, the author starts from the definition of number sense, combined with the content of mathematics in middle and lower grades, puts forward some strategies on how to cultivate number sense in elementary school.
